Skylight installation in Tonypandy: what is involved?
Skylight installation in Tonypandy means survey, supply and fit — new openings, extensions and fit-only work. We cover the CF40 district and the rest of Mid Glamorgan, with a survey before any price is fixed.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Think of skylight installation for new extensions, new openings and fit-only jobs.
From Tonypandy to Rhondda, Pontypridd and Aberdare, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Internal plaster reveal
- Upstands and flashings
- Fit only (customer-supplied units)
- Supply and fit
- New openings with joist trimming
- Fixed price in writing before work
- Making good inside included
Before you order: points to check
- Building Regulations approval (a building warrant in Scotland) may be needed
- Work at height is planned with suitable access
Planning, building control and Tonypandy
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
Read the planning permission guide before you commit to a design.

Common questions
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
Is the survey free?
Yes, for new installations. Repair visits are charged.
Do you fit rooflights bought elsewhere?
Yes. We check the product and the opening first, and our workmanship terms cover the fitting rather than the product.
Can you work alongside my builder in Tonypandy?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Tonypandy?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
